    How to save a value to a MNTP programmatically

    Hello,

    Could someone tell me how I should save a value to a Multi Node Tree Picker. I've tried saving a page Id however this is not reflected in the backoffice. Does it need to be saved in a particular format.

    Examples welcome.

    Many thanks

    Paul

    Hi Paul,

    I haven't done this but at a guess, maybe you need to pass in an IPublishedContent?

    Otherwise, it'd be good to see your code so far and we can go from there.

    Hey Paul I ran into a similar problem.

    See this thread and the helper method by Dan:

    Hi Matt,

    Thanks for the link, I've tried to no avail to use that code.

    I have managed to get it working, see code below:-

                        if (memberExists)
                {
                    IMember currentUser = ms.GetByUsername(userName);

                    if (currentUser != null)
                    {
                        var findPage = cs.GetById(pageId);

                        var loadUdi = Udi.Create(Constants.UdiEntityType.Document, findPage.Key);

                        List<string> splitPages = new List<string>();

                        if (currentUser.GetValue("favouritePages") != null)
                        {
                            splitPages = currentUser.GetValue("favouritePages").ToString().Split(',').ToList();

                            bool checkIfExists = splitPages.Any(page => page == loadUdi.ToString());

                            if (!checkIfExists)
                            {
                                splitPages.Add(loadUdi.ToString());

                                currentUser.SetValue("favouritePages", string.Join(",", splitPages));
                            }

                        }
                        else
                        {
                            splitPages.Add(loadUdi.ToString());

                            currentUser.SetValue("favouritePages", string.Join(",", splitPages));
                        }

                        ms.Save(currentUser);

                    }

                }
